CS655 Datasheet PDF - Campbell Scientific United Kingdom

Overview
   The CS650/CS655 Soil Water Content Reflectometers use innovative techniques to monitor soil volumetric water content, bulk electrical conductivity, and temperature. The probe consists of two 30-cm-long (for CS650) and two 12-cm-long (for CS655) stainless steel rods connected to a printed circuit board. The circuit board is encapsulated in epoxy and a shielded cable is attached to the circuit board for datalogger connection.

Benefits and Features
➢ Measures the following soil values:
   - volumetric water content
   - bulk electrical conductivity (EC)
   - soil temperature
   - dielectric permittivity
➢ SDI-12 output
➢ Serial connection for sensor configuration
➢ Robust water content measurement even with high bulk EC
➢ Larger sample volume reduces error from spatial variability of
   measured parameters
➢ Measurement corrected for effects of soil texture and
   electrical conductivity
